Monitoring

Munin is a great monitoring tool, which gathers performance data from the plugins running on the nodes and presents them in graphs with web interface. Munin’s graphs and web pages are generated either statically by cron jobs or dynamically upon request via Munin CGI tools. With Munin CGI, only web pages and graphs which are actually needed – requested by user’s browser – are dynamically generated. This article describes configuration of the Munin CGI with Apache web server running on Fedora 26.
